Back to school welcome discount popups

Three to four weeks before school starts in your main market, which in the US often means late July. Run reminders until the first week of term.

Bundles and spend thresholds (“free shipping over $50”) fit the season’s basket-building better than flat discounts on single items.

Most stores start at 10% off the first order or free shipping. Test a second variant before going higher: a bigger number rarely doubles signups, but it always costs margin on every first order.

After the visitor has seen enough to care: a few seconds in, after scrolling, or on exit intent. Showing it the instant someone lands from search on mobile is what search engines treat as an intrusive interstitial.
